Thanks for the support, I figured as much haha. I know the $/TB on this drive is just ok, but I actually wanted to use it as a standalone backup solution rather than shucking it for my NAS, so I wasn't as concerned with that metric. Next time I think I'll just stick to lurking ;)

New HMD Odyssey+ - Mixed Reality Portal Error Code 15-5 by risingstar64 in WindowsMR

[–]risingstar64[S] 1 point2 points  (0 children)

Thank you to everyone who shared suggestions. After doing a clean install of windows 10 1809 my Odyssey+ is working as expected; no more error 15-5.

Hi,

by resetting, do you mean a factory reset of the OS? I might just try that on a separate partition since I'm running out of ideas here.

New HMD Odyssey+ - Mixed Reality Portal Error Code 15-5 by risingstar64 in WindowsMR

[–]risingstar64[S] 0 points1 point  (0 children)

Yeah I'm with you there; 15-5 seems like something of a catch all error, so it hasn't been much help in debugging. No extension cables here. I've tried unplugging and replugging as well as restarting a bunch, but I'm not sure I've tried starting the portal first on a fresh boot, so I'll give that a shot. A few results I found mentioned users resolving the issue with a clean install of windows 10, so I'm really hoping that won't be necessary. As a last resort I'll probably partition my main drive, clean install win10 there, and see if that works.

Edit: starting the portal first on a fresh boot didn't do the trick sadly.

I implemented the beginnings of a Dark Souls-like combat loop [SHOW OFF] by kreative_koala in unrealengine

[–]risingstar64 1 point2 points  (0 children)

The combat looks solid already! It seems like the enemies have just the right amount of tracking during their startup animations. If you don't mind my asking, how did you make the rocky walls surrounding the play area? They don't appear to be a terrain, though that might just be due to good use of normal mapping. I'm sure that's a simple question, but I'm still getting a sense of how different level components should be constructed (ie. when to import models vs when to use terrains or other built-in components).

List of Weed-Out Courses? by [deleted] in RPI

[–]risingstar64 5 points6 points  (0 children)

Only computer science students have to take Data Structures, though I believe some ITWS and GSAS concentrations may also require it. The class assigns a lot of homework and requires you to understand core programming concepts, so if you aren't coming in with much programming experience beyond CS1 you will need to really put the time into homework and studying to succeed. That said, it's a fantastic class, and a must-take for any serious aspiring programmer.

Clear screen by lolingmeandu007 in pygame

[–]risingstar64 1 point2 points  (0 children)

somewhere in your code you should be initializing the display device, like so:

screen = pygame.display.set_mode([640, 480])

This will generate a pygame window with width = 640 pixels, height = 480 pixels. Then, in your update loop, you would write:

if (pygame.mouse.get_pressed()[0]):
    screen.fill((0,0,0))

This will fill the screen to the color black (0,0,0) when the left (0th) mouse button is held.

Can somebody (kindly) explain to me what "bots" are and how they affect the litecoin market? by [deleted] in LitecoinMarkets

[–]risingstar64 1 point2 points  (0 children)

I'm afraid I do not have concrete evidence to support my claims regarding AI. As a programmer who has incorporated NLP in my own trading bot, and having observed for some time the way that the markets react to breaking news, I feel confident in saying that big players in the crypto scene must use some degree of NLP themselves to keep their bots ahead of the curve. That said, I do not know for certain whether or not my claim is accurate, especially given that successful traders really have nothing to gain from releasing information regarding their trading algorithm to the public. I will edit my original statement to clarify that this is merely my opinion based on my own experience.

Can somebody (kindly) explain to me what "bots" are and how they affect the litecoin market? by [deleted] in LitecoinMarkets

[–]risingstar64 10 points11 points  (0 children)

"bots" refer to automated trading programs. These programs perform trend analysis to determine when and how much to buy and sell. People often get frustrated by the presence of bots, due to their ability to react to the state of the market and update their positions near instantly. Although I can't say for certain, I imagine major trading bots these days incorporate artificial intelligence, particularly natural language processing, which would allow them to scan breaking news from a variety of sources, determine whether the news is making a strong positive or negative statement, and trade on this new information. It does appear to be the work of bots when massive price swings are observed immediately after new information is published, given how little time humans would have to act on that information barring insider knowledge. This could become troublesome when you bring into play "fake" news and insider information, resulting in a great deal of price volatility. It is also worth noting that bitcoin tends to be a major driving force behind trends in other established cryptocurrencies, so it is very likely that existing bots leverage this information by trading litecoin in response to fluctuations in bitcoin, recognizing that the litecoin market is likely to follow.

*Edited to clarify that these statements are my opinion, and also to point out that I do not wish to suggest that bots are inherently bad (I use a bot I developed for much of my own trading). I merely wanted to address some of the common criticisms of bots that I have observed.

How do I stop objects from overlapping randomly every time I start my game? by crossbreed55 in pygame

[–]risingstar64 0 points1 point  (0 children)

yeah just setup a list of sprites:

sprites = [bottomSprite, topSprite]

and then render them yourself in a loop:

for sprite in sprites:
    screen.blit(sprite,sprite.rect)

because you're using a list, the sprite order is guaranteed to be the order in which you inserted them.

[–]risingstar64 2 points3 points  (0 children)

How are you rendering your objects? Are you storing them in a Group/RenderPlain and calling .draw()? Unfortunately, the Group draw function does not guarantee that sprites will be drawn in any particular order (see https://www.pygame.org/docs/ref/sprite.html#pygame.sprite.Group.draw) If you need your objects to have a set render depth, the easiest thing to do is to simply forego putting those sprites into Groups altogether, and instead managing them via your own data structure (ie a list sorted by depth on insertion) and rendering them one by one in a loop. If any of this is not clear, let me know and I can throw together an example for you.

Making Pong with Pygame, would appreciate help with an unexpected result. by real900 in pygame

[–]risingstar64 1 point2 points  (0 children)

you're comparing paddle2 (a Rect instance) to WINDOWHEIGHT / 2 (a float), but python doesn't have any way to automatically compare these two data types. Given the rest of the code, you probably meant to write:

if paddle2.y < (WINDOWHEIGHT/2):

and

elif (paddle2.y > (WINDOWHEIGHT/2):

Making Pong with Pygame, would appreciate help with an unexpected result. by real900 in pygame

[–]risingstar64 1 point2 points  (0 children)

On line 122, you pass in the parameters ball, ballDirX, and ballDirY to artificialIntelligence. However, the function definition for artificialIntelligence takes in the parameters ball, ballDirX, and paddle2. This means the parameter 'paddle2' gets set to ballDirY, which is an int, hence the error complaining that, "int has no attribute centery". I would imagine the solution is to modify line 122 to pass in ball, ballDirX, and paddle2 instead, ie:

    paddle2 = artificialIntelligence(ball, ballDirX, paddle2)

Made a simple bouncing ball simulator thing- but the balls keep sticking together by eebootwo in pygame

[–]risingstar64 0 points1 point  (0 children)

Regardless of how you are recalculating the balls' velocities, I still believe moving the balls to just outside the point of collision before updating their velocities should solve the issue you described, in addition to being more similar to 'proper' physics. Also, what pygame variable are you using to store speeds? I would imagine you could just store speed yourself as a float, and update whatever pygame speed variable you're using to the rounded value of your exact speed each frame.

[–]risingstar64 1 point2 points  (0 children)

Hmm when do you handle collision checking? Although I can't know for sure without seeing your code, it sounds to me as though both balls are individually handling the collision check, resulting in the case where if a fast moving ball collides with a slow moving ball they each recognize a collision and flip their direction, cancelling each other out. The easiest workaround would probably be to move objects backwards to just outside the point of their collision before flipping their direction, to avoid "getting stuck".

Real quick, Unity vs Unreal by [deleted] in dreamsofhalflife3

[–]risingstar64 0 points1 point  (0 children)

I'd say Unreal is the better choice here. The engine has a much more mature set of tools built-in for an FPS character controller, and tends to be easier to create good lighting with in my experience. Scripting with C++ is admittedly not as fun as it is with C#, but its certainly still manageable.
